This guide explains the main points to consider before speaking to a refrigeration engineer. It is general information rather than a diagnosis or site-specific food-safety instruction.

Where the ice forms matters

Ice around a door suggests a different issue from a blocked evaporator or frozen drain. Photographs can help initial triage.

Avoid damaging the equipment

Do not chip ice from coils or use uncontrolled heat. Arrange diagnosis before the condition causes further damage.

Before you call

Build a short, accurate equipment record.

Note the target temperature, actual temperature, controller display, alarms, visible ice or water, unusual sounds and the approximate time the condition changed. Include the equipment make and model if accessible without removing covers.

When to request professional help

Rapid temperature rise, repeated alarms, electrical tripping, water leaks, burning smells, unusual noise or total loss of cooling need prompt assessment. Follow your site food-safety procedure and do not remove covers or alter refrigerant controls.

Getting a clear next step

Share the site postcode, equipment type, controller display, actual temperature, symptoms and when the problem began. Useful detail helps establish whether diagnosis, repair, maintenance or a site survey is required.
